Keep Your Greenhouse Pest-Free: Prevention & Natural Control

Greenhouses create ideal growing conditions—for plants and pests. Enclosed spaces amplify infestations. Proactive hygiene and biological controls are your best defense.

Five-Point Prevention Plan

1. Weekly cleaning schedule: Remove mold/fungi immediately (spread fast in enclosure). Seasonal deep clean: remove all items, wash surfaces with hot soapy water.
2. Annual freeze-out: Remove plants 1–2 days. Open greenhouse to cold—pests die or flee. Reintroduce plants to clean space.
3. Sanitize tools & media: Wash all tools (even new) with bleach/hot water. Use sterilized potting mix—never garden soil.
4. Routine plant inspection: Check for eggs/larvae. "If it looks wrong, it is wrong." Quarantine suspect plants immediately—easier to treat one than all.
5. Beneficial insects over pesticides: Praying mantises and ladybugs prey on pests without harming crops—ideal for edible harvests.

Consistent vigilance = thriving, pest-free greenhouse.
